Give them something creative to do. Boredom is the mother of creativity.
It’s good to be bored, so they can think over things like bad life decissoons, why they are bored and why they think somebody else needs to entertain them instead of fjndjng something to do. (Or why they should do anything anyway)
There’s nothing wrong with doing nothing for a while.
The comments here, including mine, most likely won’t help you to find a solution for that boredom. ‘Bored’ is a vague term. There can be endless ways why and especially how drastic somebody is always bored. Whether that somebody is you, somebody who asked you for help or somebody who you think needs help, you know them better than anyone here.
